I'm glad you like them! Sure do, though I have no way of getting payments atm so I am doing them mainly to just get my name out there. Once I get more popular I will get a credit/debit card set up or something so that I could get payments. (Whatever it is that you use to get digital payments xD)
Would I just send them a link to the folder that I keep them in on dA and say, "Hey, here are some emblems that I have made for various ponies throughout the show, I hope you like them, it would be great if you would feature them." ?
